BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates in general to the field of computers and similar technologies, and in particular to software utilized in this field. Still more particularly, it relates to a method, system and computer-usable medium for generating and using a universal knowledge repository.

2. Description of the Related Art

In general, “big data” refers to a collection of datasets so large and complex that they become difficult to process using typical database management tools and traditional data processing approaches. These datasets can originate from a wide variety of sources, including computer systems, mobile devices, credit card transactions, television broadcasts, and medical equipment, as well as infrastructures associated with cities, sensor-equipped buildings and factories, and transportation systems. Challenges commonly associated with big data, which may be a combination of structured, unstructured, and semi-structured data, include its capture, curation, storage, search, sharing, analysis and visualization. In combination, these challenges make it difficult to efficiently process large quantities of data within tolerable time intervals.

Nonetheless, big data analytics hold the promise of extracting insights by uncovering difficult-to-discover patterns and connections, as well as providing assistance in making complex decisions by analyzing different and potentially conflicting options. As such, individuals and organizations alike can be provided new opportunities to innovate, compete, and capture value.

One aspect of big data is “dark data,” which generally refers to data that is either not collected, neglected, or underutilized. Examples of data that is not currently being collected includes location data prior to the emergence of companies such as Foursquare or social data prior to the advent companies such as Facebook. An example of data that is being collected, but is difficult to access at the right time and place, includes data associated with the side effects of certain spider bites while on a camping trip. As another example, data that is collected and available, but has not yet been productized of fully utilized, may include disease insights from population-wide healthcare records and social media feeds. As a result, a case can be made that dark data may in fact be of higher value than big data in general, especially as it can likely provide actionable insights when it is combined with readily-available data.

DETAILED DESCRIPTION

A method, system and computer-usable medium are disclosed for cognitive inference and learning operations. The present invention may be a system, a method, and/or a computer program product. The computer program product may include a computer readable storage medium (or media) having computer readable program instructions thereon for causing a processor to carry out aspects of the present invention.

The computer readable storage medium can be a tangible device that can retain and store instructions for use by an instruction execution device. The computer readable storage medium may be, for example, but is not limited to, an electronic storage device, a magnetic storage device, an optical storage device, an electromagnetic storage device, a semiconductor storage device, or any suitable combination of the foregoing. A non-exhaustive list of more specific examples of the computer readable storage medium includes the following: a portable computer diskette, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or Flash memory), a static random access memory (SRAM), a portable compact disc read-only memory (CD-ROM), a digital versatile disk (DVD), a memory stick, a floppy disk, a mechanically encoded device such as punch-cards or raised structures in a groove having instructions recorded thereon, and any suitable combination of the foregoing. A computer readable storage medium, as used herein, is not to be construed as being transitory signals per se, such as radio waves or other freely propagating electromagnetic waves, electromagnetic waves propagating through a waveguide or other transmission media (e.g., light pulses passing through a fiber-optic cable), or electrical signals transmitted through a wire.

Computer readable program instructions described herein can be downloaded to respective computing/processing devices from a computer readable storage medium or to an external computer or external storage device via a network, for example, the Internet, a local area network, a wide area network and/or a wireless network. The network may comprise copper transmission cables, optical transmission fibers, wireless transmission, routers, firewalls, switches, gateway computers and/or edge servers. A network adapter card or network interface in each computing/processing device receives computer readable program instructions from the network and forwards the computer readable program instructions for storage in a computer readable storage medium within the respective computing/processing device.

Computer readable program instructions for carrying out operations of the present invention may be assembler instructions, instruction-set-architecture (ISA) instructions, machine instructions, machine dependent instructions, microcode, firmware instructions, state-setting data, or either source code or object code written in any combination of one or more programming languages, including an object oriented programming language such as Smalltalk, C++ or the like, and conventional procedural programming languages, such as the “C” programming language or similar programming languages. The computer readable program instructions may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the user's computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider). In some embodiments, electronic circuitry including, for example, programmable logic circuitry, field-programmable gate arrays (FPGA), or programmable logic arrays (PLA) may execute the computer readable program instructions by utilizing state information of the computer readable program instructions to personalize the electronic circuitry, in order to perform aspects of the present invention.

Aspects of the present invention are described herein with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems), and computer program products according to embodiments of the invention. It will be understood that each block of the flowchart illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer readable program instructions.

These computer readable program instructions may be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks. These computer readable program instructions may also be stored in a computer readable storage medium that can direct a computer, a programmable data processing apparatus, and/or other devices to function in a particular manner, such that the computer readable storage medium having instructions stored therein comprises an article of manufacture including instructions which implement aspects of the function/act specified in the flowchart and/or block diagram block or blocks.

The computer readable program instructions may also be loaded onto a computer, other programmable data processing apparatus, or other device to cause a series of operational steps to be performed on the computer, other programmable apparatus or other device to produce a computer implemented process, such that the instructions which execute on the computer, other programmable apparatus, or other device implement the functions/acts specified in the flowchart and/or block diagram block or blocks.

The flowchart and block diagrams in the Figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods, and computer program products according to various embodiments of the present invention. In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of instructions, which comprises one or more executable instructions for implementing the specified logical function(s). In some alternative implementations, the functions noted in the block may occur out of the order noted in the figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts or carry out combinations of special purpose hardware and computer instructions.

FIG. 1 is a generalized illustration of an information processing system 100 that can be used to implement the system and method of the present invention. The information processing system 100 includes a processor (e.g., central processor unit or “CPU”) 102, input/output (I/O) devices 104, such as a display, a keyboard, a mouse, and associated controllers, a hard drive or disk storage 106, and various other subsystems 108. In various embodiments, the information processing system 100 also includes network port 110 operable to connect to a network 140, which is likewise accessible by a service provider server 142. The information processing system 100 likewise includes system memory 112, which is interconnected to the foregoing via one or more buses 114. System memory 112 further comprises operating system (OS) 116 and in various embodiments may also comprise cognitive inference and learning system (CILS) 118. In these and other embodiments, the CILS 118 may likewise comprise invention modules 120. In one embodiment, the information processing system 100 is able to download the CILS 118 from the service provider server 142. In another embodiment, the CILS 118 is provided as a service from the service provider server 142.

In various embodiments, the CILS 118 is implemented to perform various cognitive computing operations described in greater detail herein. As used herein, cognitive computing broadly refers to a class of computing involving self-learning systems that use techniques such as spatial navigation, machine vision, and pattern recognition to increasingly mimic the way the human brain works. To be more specific, earlier approaches to computing typically solved problems by executing a set of instructions codified within software. In contrast, cognitive computing approaches are data-driven, sense-making, insight-extracting, problem-solving systems that have more in common with the structure of the human brain than with the architecture of contemporary, instruction-driven computers.

To further differentiate these distinctions, traditional computers must first be programmed by humans to perform specific tasks, while cognitive systems learn from their interactions with data and humans alike, and in a sense, program themselves to perform new tasks. To summarize the difference between the two, traditional computers are designed to calculate rapidly. Cognitive systems are designed to quickly draw inferences from data and gain new knowledge.

Cognitive systems achieve these abilities by combining various aspects of artificial intelligence, natural language processing, dynamic learning, and hypothesis generation to render vast quantities of intelligible data to assist humans in making better decisions. As such, cognitive systems can be characterized as having the ability to interact naturally with people to extend what either humans, or machines, could do on their own. Furthermore, they are typically able to process natural language, multi-structured data, and experience much in the same way as humans. Moreover, they are also typically able to learn a knowledge domain based upon the best available data and get better, and more immersive, over time.

It will be appreciated that more data is currently being produced every day than was recently produced by human beings from the beginning of recorded time. Deep within this ever-growing mass of data is a class of data known as “dark data,” which includes neglected information, ambient signals, and insights that can assist organizations and individuals in augmenting their intelligence and deliver actionable insights through the implementation of cognitive applications. As used herein, cognitive applications, or “cognitive apps,” broadly refer to cloud-based, big data interpretive applications that learn from user engagement and data interactions. Such cognitive applications extract patterns and insights from dark data sources that are currently almost completely opaque. Examples of such dark data include disease insights from population-wide healthcare records and social media feeds, or from new sources of information, such as sensors monitoring pollution in delicate marine environments.

Over time, it is anticipated that cognitive applications will fundamentally change the ways in which many organizations operate as they invert current issues associated with data volume and variety to enable a smart, interactive data supply chain. Ultimately, cognitive applications hold the promise of receiving a user query and immediately providing a data-driven answer from a masked data supply chain in response. As they evolve, it is likewise anticipated that cognitive applications may enable a new class of “sixth sense” applications that intelligently detect and learn from relevant data and events to offer insights, predictions and advice rather than wait for commands. Just as web and mobile applications changed the way people access data, cognitive applications may change the way people listen to, and become empowered by, multi-structured data such as emails, social media feeds, doctors notes, transaction records, and call logs.

However, the evolution of such cognitive applications has associated challenges, such as how to detect events, ideas, images, and other content that may be of interest. For example, assuming that the role and preferences of a given user are known, how is the most relevant information discovered, prioritized, and summarized from large streams of multi-structured data such as news feeds, blogs, social media, structured data, and various knowledge bases? To further the example, what can a healthcare executive be told about their competitor's market share? Other challenges include the creation of a contextually-appropriate visual summary of responses to questions or queries.

FIG. 2 is a simplified block diagram of a cognitive inference and learning system (CILS) implemented in accordance with an embodiment of the invention. In various embodiments, the CILS 118 is implemented to incorporate a variety of processes, including semantic analysis 202, goal optimization 204, collaborative filtering 206, common sense reasoning 208, natural language processing 210, summarization 212, temporal/spatial reasoning 214, and entity resolution 216 to generate cognitive insights.

As used herein, semantic analysis 202 broadly refers to performing various analysis operations to achieve a semantic level of understanding about language by relating syntactic structures. In various embodiments, various syntactic structures are related from the levels of phrases, clauses, sentences and paragraphs, to the level of the body of content as a whole and to its language-independent meaning. In certain embodiments, the semantic analysis 202 process includes processing a target sentence to parse it into its individual parts of speech, tag sentence elements that are related to predetermined items of interest, identify dependencies between individual words, and perform co-reference resolution. For example, if a sentence states that the author really likes the hamburgers served by a particular restaurant, then the name of the “particular restaurant” is co-referenced to “hamburgers.”

As likewise used herein, goal optimization 204 broadly refers to performing multi-criteria decision making operations to achieve a given goal or target objective. In various embodiments, one or more goal optimization 204 processes are implemented by the CILS 118 to define predetermined goals, which in turn contribute to the generation of a cognitive insight. For example, goals for planning a vacation trip may include low cost (e.g., transportation and accommodations), location (e.g., by the beach), and speed (e.g., short travel time). In this example, it will be appreciated that certain goals may be in conflict with another. As a result, a cognitive insight provided by the CILS 118 to a traveler may indicate that hotel accommodations by a beach may cost more than they care to spend.

Collaborative filtering 206, as used herein, broadly refers to the process of filtering for information or patterns through the collaborative involvement of multiple agents, viewpoints, data sources, and so forth. The application of such collaborative filtering 206 processes typically involves very large and different kinds of data sets, including sensing and monitoring data, financial data, and user data of various kinds Collaborative filtering 206 may also refer to the process of making automatic predictions associated with predetermined interests of a user by collecting preferences or other information from many users. For example, if person ‘A’ has the same opinion as a person ‘B’ for a given issue ‘x’, then an assertion can be made that person ‘A’ is more likely to have the same opinion as person ‘B’ opinion on a different issue ‘y’ than to have the same opinion on issue ‘y’ as a randomly chosen person. In various embodiments, the collaborative filtering 206 process is implemented with various recommendation engines familiar to those of skill in the art to make recommendations.

As used herein, common sense reasoning 208 broadly refers to simulating the human ability to make deductions from common facts they inherently know. Such deductions may be made from inherent knowledge about the physical properties, purpose, intentions and possible behavior of ordinary things, such as people, animals, objects, devices, and so on. In various embodiments, common sense reasoning 208 processes are implemented to assist the CILS 118 in understanding and disambiguating words within a predetermined context. In certain embodiments, the common sense reasoning 208 processes are implemented to allow the CILS 118 to generate text or phrases related to a target word or phrase to perform deeper searches for the same terms. It will be appreciated that if the context of a word is better understood, then a common sense understanding of the word can then be used to assist in finding better or more accurate information. In certain embodiments, this better or more accurate understanding of the context of a word, and its related information, allows the CILS 118 to make more accurate deductions, which are in turn used to generate cognitive insights.

As likewise used herein, natural language processing (NLP) 210 broadly refers to interactions with a system, such as the CILS 118, through the use of human, or natural, languages. In various embodiments, various NLP 210 processes are implemented by the CILS 118 to achieve natural language understanding, which enables it to not only derive meaning from human or natural language input, but to also generate natural language output.

Summarization 212, as used herein, broadly refers to processing a set of information, organizing and ranking it, and then generating a corresponding summary. As an example, a news article may be processed to identify its primary topic and associated observations, which are then extracted, ranked, and then presented to the user. As another example, page ranking operations may be performed on the same news article to identify individual sentences, rank them, order them, and determine which of the sentences are most impactful in describing the article and its content. As yet another example, a structured data record, such as a patient's electronic medical record (EMR), may be processed using the summarization 212 process to generate sentences and phrases that describes the content of the EMR. In various embodiments, various summarization 212 processes are implemented by the CILS 118 to generate summarizations of content streams, which are in turn used to generate cognitive insights.

As used herein, temporal/spatial reasoning 214 broadly refers to reasoning based upon qualitative abstractions of temporal and spatial aspects of common sense knowledge, described in greater detail herein. For example, it is not uncommon for a predetermined set of data to change over time. Likewise, other attributes, such as its associated metadata, may likewise change over time. As a result, these changes may affect the context of the data. To further the example, the context of asking someone what they believe they should be doing at 3:00 in the afternoon during the workday while they are at work may be quite different that asking the same user the same question at 3:00 on a Sunday afternoon when they are at home. In various embodiments, various temporal/spatial reasoning 214 processes are implemented by the CILS 118 to determine the context of queries, and associated data, which are in turn used to generate cognitive insights.

As likewise used herein, entity resolution 216 broadly refers to the process of finding elements in a set of data that refer to the same entity across different data sources (e.g., structured, non-structured, streams, devices, etc.), where the target entity does not share a common identifier. In various embodiments, the entity resolution 216 process is implemented by the CILS 118 to identify significant nouns, adjectives, phrases or sentence elements that represent various predetermined entities within one or more domains. From the foregoing, it will be appreciated that the implementation of one or more of the semantic analysis 202, goal optimization 204, collaborative filtering 206, common sense reasoning 208, natural language processing 210, summarization 212, temporal/spatial reasoning 214, and entity resolution 216 processes by the CILS 118 can facilitate the generation of a semantic, cognitive model.

In various embodiments, the CILS 118 receives ambient signals 220, curated data 222, and learned knowledge, which is then processed by the CILS 118 to generate one or more cognitive graphs 226. In turn, the one or more cognitive graphs 226 are further used by the CILS 118 to generate cognitive insight streams, which are then delivered to one or more destinations 230, as described in greater detail herein.

As used herein, ambient signals 220 broadly refer to input signals, or other data streams, that may contain data providing additional insight or context to the curated data 222 and learned knowledge 224 received by the CILS 118. For example, ambient signals may allow the CILS 118 to understand that a user is currently using their mobile device, at location ‘x’, at time ‘y’, doing activity ‘z’. To further the example, there is a difference between the user using their mobile device while they are on an airplane versus using their mobile device after landing at an airport and walking between one terminal and another. To extend the example even further, ambient signals may add additional context, such as the user is in the middle of a three leg trip and has two hours before their next flight. Further, they may be in terminal A1, but their next flight is out of C1, it is lunchtime, and they want to know the best place to eat. Given the available time the user has, their current location, restaurants that are proximate to their predicted route, and other factors such as food preferences, the CILS 118 can perform various cognitive operations and provide a recommendation for where the user can eat.

In various embodiments, the curated data 222 may include structured, unstructured, social, public, private, streaming, device or other types of data described in greater detail herein. In certain embodiments, the learned knowledge 224 is based upon past observations and feedback from the presentation of prior cognitive insight streams and recommendations. In various embodiments, the learned knowledge 224 is provided via a feedback look that provides the learned knowledge 224 in the form of a learning stream of data.

As likewise used herein, a cognitive graph 226 refers to a representation of expert knowledge, associated with individuals and groups over a period of time, to depict relationships between people, places, and things using words, ideas, audio and images. As such, it is a machine-readable formalism for knowledge representation that provides a common framework allowing data and knowledge to be shared and reused across user, application, organization, and community boundaries.

In various embodiments, the information contained in, and referenced by, a cognitive graph 226 is derived from many sources (e.g., public, private, social, device), such as curated data 222. In certain of these embodiments, the cognitive graph 226 assists in the identification and organization of information associated with how people, places and things are related to one other. In various embodiments, the cognitive graph 226 enables automated agents, described in greater detail herein, to access the Web more intelligently, enumerate inferences through utilization of curated, structured data 222, and provide answers to questions by serving as a computational knowledge engine.

In certain embodiments, the cognitive graph 226 not only elicits and maps expert knowledge by deriving associations from data, it also renders higher level insights and accounts for knowledge creation through collaborative knowledge modeling. In various embodiments, the cognitive graph 226 is a machine-readable, declarative memory system that stores and learns both episodic memory (e.g., specific personal experiences associated with an individual or entity), and semantic memory, which stores factual information (e.g., geo location of an airport or restaurant).

For example, the cognitive graph 226 may know that a given airport is a place, and that there is a list of related places such as hotels, restaurants and departure gates. Furthermore, the cognitive graph 226 may know that people such as business travelers, families and college students use the airport to board flights from various carriers, eat at various restaurants, or shop at certain retail stores. The cognitive graph 226 may also have knowledge about the key attributes from various retail rating sites that travelers have used to describe the food and their experience at various venues in the airport over the past six months.

In certain embodiments, the cognitive insight stream 228 is bidirectional, and supports flows of information both too and from destinations 230. In these embodiments, the first flow is generated in response to receiving a query, and subsequently delivered to one or more destinations 230. The second flow is generated in response to detecting information about a user of one or more of the destinations 230. Such use results in the provision of information to the CILS 118. In response, the CILS 118 processes that information, in the context of what it knows about the user, and provides additional information to the user, such as a recommendation. In various embodiments, the cognitive insight stream 228 is configured to be provided in a “push” stream configuration familiar to those of skill in the art. In certain embodiments, the cognitive insight stream 228 is implemented to use natural language approaches familiar to skilled practitioners of the art to support interactions with a user.

In various embodiments, the cognitive insight stream 228 may include a stream of visualized insights. As used herein, visualized insights broadly refers to cognitive insights that are presented in a visual manner, such as a map, an infographic, images, and so forth. In certain embodiments, these visualized insights may include various cognitive insights, such as “What happened?”, “What do I know about it?”, “What is likely to happen next?”, or “What should I do about it?” In these embodiments, the cognitive insight stream is generated by various cognitive agents, which are applied to various sources, datasets, and cognitive graphs. As used herein, a cognitive agent broadly refers to a computer program that performs a task with minimum specific directions from users and learns from each interaction with data and human users.

In various embodiments, the CILS 118 delivers Cognition as a Service (CaaS). As such, it provides a cloud-based development and execution platform that allow various cognitive applications and services to function more intelligently and intuitively. In certain embodiments, cognitive applications powered by the CILS 118 are able to think and interact with users as intelligent virtual assistants. As a result, users are able to interact with such cognitive applications by asking them questions and giving them commands. In response, these cognitive applications will be able to assist the user in completing tasks and managing their work more efficiently.

In these and other embodiments, the CILS 118 can operate as an analytics platform to process big data, and dark data as well, to provide data analytics through a public, private or hybrid cloud environment. As used herein, cloud analytics broadly refers to a service model wherein data sources, data models, processing applications, computing power, analytic models, and sharing or storage of results are implemented within a cloud environment to perform one or more aspects of analytics.

In various embodiments, users submit queries and computation requests in a natural language format to the CILS 118. In response, they are provided with a ranked list of relevant answers and aggregated information with useful links and pertinent visualizations through a graphical representation. In these embodiments, the cognitive graph 226 generates semantic and temporal maps to reflect the organization of unstructured data and to facilitate meaningful learning from potentially millions of lines of text, much in the same way as arbitrary syllables strung together create meaning through the concept of language.

FIG. 3 is a simplified block diagram of a cognitive inference and learning system (CILS) reference model implemented in accordance with an embodiment of the invention. In this embodiment, the CILS reference model is associated with the CILS 118 shown in FIG. 2. As shown in FIG. 3, the CILS 118 includes client applications 302, application accelerators 306, a cognitive platform 310, and cloud infrastructure 340. In various embodiments, the client applications 302 include cognitive applications 304, which are implemented to understand and adapt to the user, not the other way around, by natively accepting and understanding human forms of communication, such as natural language text, audio, images, video, and so forth.

In these and other embodiments, the cognitive applications 304 possess situational and temporal awareness based upon ambient signals from users and data, which facilitates understanding the user's intent, content, context and meaning to drive goal-driven dialogs and outcomes. Further, they are designed to gain knowledge over time from a wide variety of structured, non-structured, and device data sources, continuously interpreting and autonomously reprogramming themselves to better understand a given domain. As such, they are well-suited to support human decision making, by proactively providing trusted advice, offers and recommendations while respecting user privacy and permissions.

In various embodiments, the application accelerators 306 include a cognitive application framework 308. In certain embodiments, the application accelerators 306 and the cognitive application framework 308 support various plug-ins and components that facilitate the creation of client applications 302 and cognitive applications 304. In various embodiments, the application accelerators 306 include widgets, user interface (UI) components, reports, charts, and back-end integration components familiar to those of skill in the art.

As likewise shown in FIG. 3, the cognitive platform 310 includes a management console 312, a development environment 314, application program interfaces (APIs) 316, sourcing agents 318, a cognitive engine 320, destination agents 336, and platform data 338, all of which are described in greater detail herein. In various embodiments, the management console 312 is implemented to manage accounts and projects, along with user-specific metadata that is used to drive processes and operations within the cognitive platform 310 for a predetermined project.

In certain embodiments, the development environment 314 is implemented to create custom extensions to the CILS 118 shown in FIG. 2. In various embodiments, the development environment 314 is implemented for the development of a custom application, which may subsequently be deployed in a public, private or hybrid cloud environment. In certain embodiments, the development environment 314 is implemented for the development of a custom sourcing agent, a custom bridging agent, a custom destination agent, or various analytics applications or extensions.

In various embodiments, the APIs 316 are implemented to build and manage predetermined cognitive applications 304, described in greater detail herein, which are then executed on the cognitive platform 310 to generate cognitive insights. Likewise, the sourcing agents 318 are implemented in various embodiments to source a variety of multi-site, multi-structured source streams of data described in greater detail herein. In various embodiments, the cognitive engine 320 includes a dataset engine 322, a graph query engine 326, an insight/learning engine 330, and foundation components 334. In certain embodiments, the dataset engine 322 is implemented to establish and maintain a dynamic data ingestion and enrichment pipeline. In these and other embodiments, the dataset engine 322 may be implemented to orchestrate one or more sourcing agents 318 to source data. Once the data is sourced, the data set engine 322 performs data enriching and other data processing operations, described in greater detail herein, and generates one or more sub-graphs that are subsequently incorporated into a target cognitive graph.

In various embodiments, the graph query engine 326 is implemented to receive and process queries such that they can be bridged into a cognitive graph, as described in greater detail herein, through the use of a bridging agent. In certain embodiments, the graph query engine 326 performs various natural language processing (NLP), familiar to skilled practitioners of the art, to process the queries. In various embodiments, the insight/learning engine 330 is implemented to encapsulate a predetermined algorithm, which is then applied to a cognitive graph to generate a result, such as a cognitive insight or a recommendation. In certain embodiments, one or more such algorithms may contribute to answering a specific question and provide additional cognitive insights or recommendations. In various embodiments, two or more of the dataset engine 322, the graph query engine 326, and the insight/learning engine 330 may be implemented to operate collaboratively to generate a cognitive insight or recommendation. In certain embodiments, one or more of the dataset engine 322, the graph query engine 326, and the insight/learning engine 330 may operate autonomously to generate a cognitive insight or recommendation.

The foundation components 334 shown in FIG. 3 include various reusable components, familiar to those of skill in the art, which are used in various embodiments to enable the dataset engine 322, the graph query engine 326, and the insight/learning engine 330 to perform their respective operations and processes. Examples of such foundation components 334 include natural language processing (NLP) components and core algorithms, such as cognitive algorithms.

In certain embodiments, the cognitive insight API 410 is implemented to subscribe to, or request, such predetermined outputs.

In various embodiments, the sourcing agents 318 may include a batch upload 414 agent, an API connectors 415 agent, a real-time streams 416 agent, a Structured Query Language (SQL)/Not Only SQL (NoSQL) databases 417 agent, a message engines 418 agent, and one or more custom sourcing 420 agents. Skilled practitioners of the art will realize that other types of sourcing agents 318 may be used in various embodiments and the foregoing is not intended to limit the spirit, scope or intent of the invention. In various embodiments, the sourcing agents 318 are implemented to source a variety of multi-site, multi-structured source streams of data described in greater detail herein. In certain embodiments, each of the sourcing agents 318 has a corresponding API.

In various embodiments, the batch uploading 414 agent is implemented for batch uploading of data to the cognitive platform 310. In these embodiments, the uploaded data may include a single data element, a single data record or file, or a plurality of data records or files. In certain embodiments, the data may be uploaded from more than one source and the uploaded data may be in a homogenous or heterogeneous form. In various embodiments, the API connectors 415 agent is implemented to manage interactions with one or more predetermined APIs that are external to the cognitive platform 310. As an example, Associated Press® may have their own API for news stories, Expedia® for travel information, or the National Weather Service for weather information. In these examples, the API connectors 415 agent would be implemented to determine how to respectively interact with each organization's API such that the cognitive platform 310 can receive information.

In various embodiments, the real-time streams 416 agent is implemented to receive various streams of data, such as social media streams (e.g., Twitter feeds) or other data streams (e.g., device data streams). In these embodiments, the streams of data are received in near-real-time. In certain embodiments, the data streams include temporal attributes.

In various embodiments, the custom sourcing agents 420, which are purpose-built, are developed through the use of the development environment 314, described in greater detail herein. Examples of custom sourcing agents 420 include sourcing agents for various electronic medical record (EMR) systems at various healthcare facilities. Such EMR systems typically collect a variety of healthcare information, much of it the same, yet it may be collected, stored and provided in different ways. In this example, the custom sourcing agents 420 allow the cognitive platform 310 to receive information from each disparate healthcare source.

In various embodiments, the cognitive engine 320 includes a dataset engine 322, a graph engine 326, an insight/learning engine 330, learning agents 434, and foundation components 334. In these and other embodiments, the dataset engine 322 is implemented as described in greater detail to establish and maintain a dynamic data ingestion and enrichment pipeline. In various embodiments, the dataset engine 322 may include a pipelines 422 component, an enrichment 423 component, a storage component 424, and one or more enrichment agents 425.

In various embodiments, the pipelines 422 component is implemented to ingest various data provided by the sourcing agents 318. Once ingested, this data is converted by the pipelines 422 component into streams of data for processing. In certain embodiments, these managed streams are provided to the enrichment 423 component, which performs data enrichment operations familiar to those of skill in the art. As an example, a data stream may be sourced from Associated Press® by a sourcing agent 318 and provided to the dataset engine 322. The pipelines 422 component receives the data stream and routes it to the enrichment 423 component, which then enriches the data stream by performing sentiment analysis, geotagging, and entity detection operations to generate an enriched data stream. In certain embodiments, the enrichment operations include filtering operations familiar to skilled practitioners of the art. To further the preceding example, the Associated Press® data stream may be filtered by a predetermined geography attribute to generate an enriched data stream.

The enriched data stream is then subsequently stored, as described in greater detail herein, in a predetermined location. In various embodiments, the enriched data stream is cached by the storage 424 component to provide a local version of the enriched data stream. In certain embodiments, the cached, enriched data stream is implemented to be “replayed” by the cognitive engine 320. In one embodiment, the replaying of the cached, enriched data stream allows incremental ingestion of the enriched data stream instead of ingesting the entire enriched data stream at one time. In various embodiments, one or more enrichment agents 425 are implemented to be invoked by the enrichment component 423 to perform one or more enrichment operations described in greater detail herein.

In various embodiments, the graph query engine 326 is implemented to receive and process queries such that they can be bridged into a cognitive graph, as described in greater detail herein, through the use of a bridging agent.

In various embodiments, the translate 427 component is implemented to convert the processed queries provided by the query 426 component into a form that can be used to query a target cognitive graph. To further differentiate the distinction between the functionality respectively provided by the query 426 and translate 427 components, the query 426 component is oriented toward understanding a query from a user. In contrast, the translate 427 component is oriented to translating a query that is understood into a form that can be used to query a cognitive graph.

In various embodiments, the bridge 428 component is implemented to generate an answer to a query provided by the translate 427 component. In certain embodiments, the bridge 428 component is implemented to provide domain-specific responses when bridging a translated query to a cognitive graph. For example, the same query bridged to a target cognitive graph by the bridge 428 component may result in different answers for different domains, dependent upon domain-specific bridging operations performed by the bridge 428 component.

To further differentiate the distinction between the translate 427 component and the bridging 428 component, the translate 427 component relates to a general domain translation of a question. In contrast, the bridging 428 component allows the question to be asked in the context of a specific domain (e.g., healthcare, travel, etc.), given what is known about the data. In certain embodiments, the bridging 428 component is implemented to process what is known about the translated query, in the context of the user, to provide an answer that is relevant to a specific domain.

As an example, a user may ask, “Where should I eat today?” If the user has been prescribed a particular health regimen, the bridging 428 component may suggest a restaurant with a “heart healthy” menu. However, if the user is a business traveler, the bridging 428 component may suggest the nearest restaurant that has the user's favorite food. In various embodiments, the bridging 428 component may provide answers, or suggestions, that are composed and ranked according to a specific domain of use. In various embodiments, the bridging agent 429 is implemented to interact with the bridging component 428 to perform bridging operations described in greater detail herein. In these embodiments, the bridging agent interprets a translated query generated by the query 426 component within a predetermined user context, and then maps it to predetermined nodes and links within a target cognitive graph.

In various embodiments, the insight/learning engine 330 is implemented to encapsulate a predetermined algorithm, which is then applied to a target cognitive graph to generate a result, such as a cognitive insight or a recommendation. In certain embodiments, one or more such algorithms may contribute to answering a specific question and provide additional cognitive insights or recommendations. In these and other embodiments, the insight/learning engine 330 is implemented to perform insight/learning operations, described in greater detail herein. In various embodiments, the insight/learning engine 330 may include a discover/visibility 430 component, a predict 431 component, a rank/recommend 432 component, and one or more insight 433 agents.

In certain embodiments, the predict 431 component is implemented to perform predictive operations to provide insight into what may next occur for a predetermined topic. In various embodiments, the rank/recommend 432 component is implemented to perform ranking and recommendation operations to provide a user prioritized recommendations associated with a provided cognitive insight.

In certain embodiments, the insight/learning engine 330 may include additional components. For example the additional components may include classification algorithms, clustering algorithms, and so forth. Skilled practitioners of the art will realize that many such additional components are possible and that the foregoing is not intended to limit the spirit, scope or intent of the invention. In various embodiments, the insights agents 433 are implemented to create a visual data story, highlighting user-specific insights, relationships and recommendations. As a result, it can share, operationalize, or track business insights in various embodiments. In various embodiments, the learning agent 434 work in the background to continually update the cognitive graph, as described in greater detail herein, from each unique interaction with data and users.

In certain embodiments, the data may be provided to more than one cognitive data consumer and the provided data may be in a homogenous or heterogeneous form. In various embodiments, the message engines 443 agent is implemented to provide cognitive insight data to one or more message engines, such as a message queue (MQ) system, a message bus, a message broker, an enterprise service bus (ESB), and so forth. Skilled practitioners of the art will realize that there are many such examples of message engines with which the message engines 443 agent may interact and the foregoing is not intended to limit the spirit, scope or intent of the invention.

In various embodiments, the custom destination agents 420, which are purpose-built, are developed through the use of the development environment 314, described in greater detail herein. Examples of custom destination agents 420 include destination agents for various electronic medical record (EMR) systems at various healthcare facilities. Such EMR systems typically collect a variety of healthcare information, much of it the same, yet it may be collected, stored and provided in different ways. In this example, the custom destination agents 420 allow such EMR systems to receive cognitive insight data in a form they can use.

In various embodiments, data that has been cleansed, normalized and enriched by the dataset engine, as described in greater detail herein, is provided by a destination agent 336 to a predetermined destination, likewise described in greater detail herein. In these embodiments, neither the graph query engine 326 nor the insight/learning engine 330 are implemented to perform their respective functions.

In various embodiments, the foundation components 334 are implemented to enable the dataset engine 322, the graph query engine 326, and the insight/learning engine 330 to perform their respective operations and processes.

In various embodiments, the dynamic pipeline engine 438 is implemented to interact with the dataset engine 322 to perform various operations related to receiving one or more sets of data from one or more sourcing agents, apply enrichment to the data, and then provide the enriched data to a predetermined destination. In these and other embodiments, the dynamic pipeline engine 438 manages the distribution of these various operations to a predetermined compute cluster and tracks versioning of the data as it is processed across various distributed computing resources. In certain embodiments, the dynamic pipeline engine 438 is implemented to perform data sovereignty management operations to maintain sovereignty of the data.

In various embodiments, the platform data 338 includes various data repositories, described in greater detail herein, that are accessed by the cognitive platform 310 to generate cognitive insights. In these embodiments, the platform data 338 repositories may include repositories of dataset metadata 456, cognitive graphs 457, models 459, crawl data 460, and management metadata 461. In various embodiments, the dataset metadata 456 is associated with curated data 458 contained in the repository of cognitive graphs 457. In these and other embodiments, the repository of dataset metadata 456 contains dataset metadata that supports operations performed by the storage 424 component of the dataset engine 322. For example, if a Mongo® NoSQL database with ten million items is being processed, and the cognitive platform 310 fails after ingesting nine million of the items, then the dataset metadata 456 may be able to provide a checkpoint that allows ingestion to continue at the point of failure instead restarting the ingestion process.

Those of skill in the art will realize that the use of such dataset metadata 456 in various embodiments allows the dataset engine 322 to be stateful. In certain embodiments, the dataset metadata 456 allows support of versioning. For example versioning may be used to track versions of modifications made to data, such as in data enrichment processes described in greater detail herein. As another example, geotagging information may have been applied to a set of data during a first enrichment process, which creates a first version of enriched data. Adding sentiment data to the same million records during a second enrichment process creates a second version of enriched data. In this example, the dataset metadata stored in the dataset metadata 456 provides tracking of the different versions of the enriched data and the differences between the two.

In various embodiments, these CILS operations may include a perceive 506 phase, a relate 508 phase, an operate 510 phase, a process and execute 512 phase, and a learn 514 phase. In these and other embodiments, the CILS 118 shown in FIG. 2 is implemented to mimic cognitive processes associated with the human brain. In various embodiments, the CILS operations are performed through the implementation of a cognitive platform 310, described in greater detail herein. In these and other embodiments, the cognitive platform 310 may be implemented within a cloud analytics infrastructure 344, which in turn is implemented within a cloud infrastructure 340, likewise described in greater detail herein.

In various embodiments, multi-site, multi-structured source streams 504 are provided by sourcing agents, as described in greater detail herein. In these embodiments, the source streams 504 are dynamically ingested in real-time during the perceive 506 phase, and based upon a predetermined context, extraction, parsing, and tagging operations are performed on language, text and images contained in the source streams 504.

As an example, a first query from a user may be submitted to the CILS system, which in turn generates a first cognitive insight, which is then provided to the user. In response, the user may respond by providing a first response, or perhaps a second query, either of which is provided in the same context as the first query. The CILS receives the first response or second query, performs various CILS operations, and provides the user a second cognitive insight. As before, the user may respond with a second response or a third query, again in the context of the first query. Once again, the CILS performs various CILS operations and provides the user a third cognitive insight, and so forth. In this example, the provision of cognitive insights to the user, and their various associated responses, results in unfolding interactions 522, which in turn result in a stateful dialog that evolves over time. Skilled practitioners of the art will likewise realize that such unfolding interactions 522, occur outside of the CILS operations performed by the cognitive platform 310.

FIG. 6 depicts the lifecycle of CILS agents implemented in accordance with an embodiment of the invention to perform CILS operations. In various embodiments, the CILS agents lifecycle 602 may include implementation of a sourcing 318 agent, an enrichment 425 agent, a bridging 429 agent, an insight 433 agent, a destination 336 agent, and a learning 434 agent. In these embodiments, the sourcing 318 agent is implemented to source a variety of multi-site, multi-structured source streams of data described in greater detail herein. These sourced data streams are then provided to an enrichment 425 agent, which then invokes an enrichment component to perform enrichment operations to generate enriched data streams, likewise described in greater detail herein.

The enriched data streams are then provided to a bridging 429 agent, which is used to perform bridging operations described in greater detail herein. In turn, the results of the bridging operations are provided to an insight 433 agent, which is implemented as described in greater detail herein to create a visual data story, highlighting user-specific insights, relationships and recommendations. The resulting visual data story is then provided to a destination 336 agent, which is implemented to publish cognitive insights to a consumer of cognitive insight data, likewise as described in greater detail herein. In response, the consumer of cognitive insight data provides feedback to a learning 434 agent, which is implemented as described in greater detail herein to provide the feedback to the sourcing agent 318, at which point the CILS agents lifecycle 602 is continued. From the foregoing, skilled practitioners of the art will recognize that each iteration of the cognitive agents lifecycle 602 provides more informed cognitive insights.

FIG. 7 is a simplified block diagram of a plurality of cognitive platforms implemented in accordance with an embodiment of the invention within a hybrid cloud infrastructure. In this embodiment, the hybrid cloud infrastructure 740 includes a cognitive cloud management 342 component, a hosted 704 cognitive cloud environment, and a private 706 network environment. As shown in FIG. 7, the hosted 704 cognitive cloud environment includes a hosted 710 cognitive platform, such as the cognitive platform 310 shown in FIGS. 3, 4 a, and 4 b. In various embodiments, the hosted 704 cognitive cloud environment may also include a hosted 718 universal knowledge repository and one or more repositories of curated public data 714 and licensed data 716. Likewise, the hosted 710 cognitive platform may also include a hosted 712 analytics infrastructure, such as the cloud analytics infrastructure 344 shown in FIGS. 3 and 4 c.

As likewise shown in FIG. 7, the private 706 network environment includes a private 720 cognitive platform, such as the cognitive platform 310 shown in FIGS. 3, 4 a, and 4 b. In various embodiments, the private 706 network cognitive cloud environment may also include a private 728 universal knowledge repository and one or more repositories of application data 724 and private data 726. Likewise, the private 720 cognitive platform may also include a private 722 analytics infrastructure, such as the cloud analytics infrastructure 344 shown in FIGS. 3 and 4 c. In certain embodiments, the private 706 network environment may have one or more private 736 cognitive applications implemented to interact with the private 720 cognitive platform.

As used herein, a universal knowledge repository broadly refers to a collection of knowledge elements that can be used in various embodiments to generate one or more cognitive insights described in greater detail herein. In various embodiments, these knowledge elements may include facts (e.g., milk is a dairy product), information (e.g., an answer to a question), descriptions (e.g., the color of an automobile), skills (e.g., the ability to install plumbing fixtures), and other classes of knowledge familiar to those of skill in the art. In these embodiments, the knowledge elements may be explicit or implicit. As an example, the fact that water freezes at zero degrees centigrade would be an explicit knowledge element, while the fact that an automobile mechanic knows how to repair an automobile would be an implicit knowledge element.

In certain embodiments, the knowledge elements within a universal knowledge repository may also include statements, assertions, beliefs, perceptions, preferences, sentiments, attitudes or opinions associated with a person or a group. As an example, user ‘A’ may prefer the pizza served by a first restaurant, while user ‘B’ may prefer the pizza served by a second restaurant. Furthermore, both user ‘A’ and ‘B’ are firmly of the opinion that the first and second restaurants respectively serve the very best pizza available. In this example, the respective preferences and opinions of users ‘A’ and B′ regarding the first and second restaurant may be included in the universal knowledge repository 880 as they are not contradictory. Instead, they are simply knowledge elements respectively associated with the two users and can be used in various embodiments for the generation of various cognitive insights, as described in greater detail herein.

In various embodiments, individual knowledge elements respectively associated with the hosted 718 and private 728 universal knowledge repositories may be distributed. In one embodiment, the distributed knowledge elements may be stored in a plurality of data stores familiar to skilled practitioners of the art. In this embodiment, the distributed knowledge elements may be logically unified for various implementations of the hosted 718 and private 728 universal knowledge repositories. In certain embodiments, the hosted 718 and private 728 universal knowledge repositories may be respectively implemented in the form of a hosted or private universal cognitive graph. In these embodiments, nodes within the hosted or private universal graph contain one or more knowledge elements.

In various embodiments, a secure tunnel 730, such as a virtual private network (VPN) tunnel, is implemented to allow the hosted 710 cognitive platform and the private 720 cognitive platform to communicate with one another. In these various embodiments, the ability to communicate with one another allows the hosted 710 and private 720 cognitive platforms to work collaboratively when generating cognitive insights described in greater detail herein. In various embodiments, the hosted 710 cognitive platform accesses knowledge elements stored in the hosted 718 universal knowledge repository and data stored in the repositories of curated public data 714 and licensed data 716 to generate various cognitive insights. In certain embodiments, the resulting cognitive insights are then provided to the private 720 cognitive platform, which in turn provides them to the one or more private cognitive applications 736.

In various embodiments, the private 720 cognitive platform accesses knowledge elements stored in the private 728 universal knowledge repository and data stored in the repositories of application data 724 and private data 726 to generate various cognitive insights. In turn, the resulting cognitive insights are then provided to the one or more private cognitive applications 736. In certain embodiments, the private 720 cognitive platform accesses knowledge elements stored in the hosted 718 and private 728 universal knowledge repositories and data stored in the repositories of curated public data 714, licensed data 716, application data 724 and private data 726 to generate various cognitive insights. In these embodiments, the resulting cognitive insights are in turn provided to the one or more private cognitive applications 736.

In various embodiments, the secure tunnel 730 is implemented for the hosted 710 cognitive platform to provide 732 predetermined data and knowledge elements to the private 720 cognitive platform. In one embodiment, the provision 732 of predetermined knowledge elements allows the hosted 718 universal knowledge repository to be replicated as the private 728 universal knowledge repository. In another embodiment, the provision 732 of predetermined knowledge elements allows the hosted 718 universal knowledge repository to provide updates 734 to the private 728 universal knowledge repository. In certain embodiments, the updates 734 to the private 728 universal knowledge repository do not overwrite other data. Instead, the updates 734 are simply added to the private 728 universal knowledge repository.

In one embodiment, knowledge elements that are added to the private 728 universal knowledge repository are not provided to the hosted 718 universal knowledge repository. As an example, an airline may not wish to share private information related to its customer's flights, the price paid for tickets, their awards program status, and so forth. In another embodiment, predetermined knowledge elements that are added to the private 728 universal knowledge repository may be provided to the hosted 718 universal knowledge repository. As an example, the operator of the private 720 cognitive platform may decide to license predetermined knowledge elements stored in the private 728 universal knowledge repository to the operator of the hosted 710 cognitive platform. To continue the example, certain knowledge elements stored in the private 728 universal knowledge repository may be anonymized prior to being provided for inclusion in the hosted 718 universal knowledge repository. In one embodiment, only private knowledge elements are stored in the private 728 universal knowledge repository. In this embodiment, the private 720 cognitive platform may use knowledge elements stored in both the hosted 718 and private 728 universal knowledge repositories to generate cognitive insights. Skilled practitioners of the art will recognize that many such embodiments are possible and the foregoing is not intended to limit the spirit, scope or intent of the invention.

FIG. 8 is a simplified process flow diagram of composite cognitive insight generation and feedback operations performed in accordance with an embodiment of the invention. As used herein, a composite cognitive insight broadly refers to a set of cognitive insights generated as a result of orchestrating a predetermined set of independent cognitive agents, referred to herein as insight agents. In various embodiments, the insight agents use a cognitive graph, such as an application cognitive graph 882 as their data source to respectively generate individual cognitive insights. As used herein, an application cognitive graph 882 broadly refers to a cognitive graph that is associated with a predetermined cognitive application 304. In certain embodiments, different cognitive applications 304 may interact with different application cognitive graphs 882 to generate individual cognitive insights for a user. In various embodiments, the resulting individual cognitive insights are then composed to generate a set of cognitive composite insights, which in turn is provided to a user in the form of a cognitive insight summary 848.

In various embodiments, the orchestration of the selected insight agents is performed by the cognitive insight/learning engine 330 shown in FIGS. 3 and 4 a. In certain embodiments, a predetermined subset of insight agents is selected to provide composite cognitive insights to satisfy a graph query 844, a contextual situation, or some combination thereof. For example, it may be determined, as described in greater detail herein, that a particular subset of insight agents may be suited to provide a composite cognitive insight related to a particular user of a particular device, at a particular location, at a particular time, for a particular purpose.

In certain embodiments, the insight agents are selected for orchestration as a result of receiving direct or indirect input data 842 from a user. In various embodiments, the direct user input may be a natural language inquiry. In certain embodiments, the indirect user input data 842 may include the location of a user's device or the purpose for which it is being used. As an example, the Geographical Positioning System (GPS) coordinates of the location of a user's mobile device may be received as indirect user input data 842. As another example, a user may be using the integrated camera of their mobile device to take a photograph of a location, such as a restaurant, or an item, such as a food product. In certain embodiments, the direct or indirect user input data 842 may include personal information that can be used to identify the user. Skilled practitioners of the art will recognize that many such embodiments are possible and the foregoing is not intended to limit the spirit, scope or intent of the invention.

In various embodiments, composite cognitive insight generation and feedback operations may be performed in various phases. In this embodiment, these phases include a data lifecycle 840 phase, a learning 838 phase, and an application/insight composition 840 phase. In the data lifecycle 836 phase, a predetermined instantiation of a cognitive platform 810 sources social data 812, public data 814, licensed data 816, and proprietary data 818 from various sources as described in greater detail herein. In various embodiments, an example of a cognitive platform 810 instantiation is the cognitive platform 310 shown in FIGS. 3, 4 a, and 4 b. In this embodiment, the instantiation of a cognitive platform 810 includes a source 806 component, a process 808 component, a deliver 810 component, a cleanse 820 component, an enrich 822 component, a filter/transform 824 component, and a repair/reject 826 component. Likewise, as shown in FIG. 8, the process 808 component includes a repository of models 828, described in greater detail herein.

In various embodiments, the process 808 component is implemented to perform various composite insight generation and other processing operations described in greater detail herein. In these embodiments, the process 808 component is implemented to interact with the source 806 component, which in turn is implemented to perform various data sourcing operations described in greater detail herein. In various embodiments, the sourcing operations are performed by one or more sourcing agents, as likewise described in greater detail herein. The resulting sourced data is then provided to the process 808 component. In turn, the process 808 component is implemented to interact with the cleanse 820 component, which is implemented to perform various data cleansing operations familiar to those of skill in the art. As an example, the cleanse 820 component may perform data normalization or pruning operations, likewise known to skilled practitioners of the art. In certain embodiments, the cleanse 820 component may be implemented to interact with the repair/reject 826 component, which in turn is implemented to perform various data repair or data rejection operations known to those of skill in the art.

Once data cleansing, repair and rejection operations are completed, the process 808 component is implemented to interact with the enrich 822 component, which is implemented in various embodiments to perform various data enrichment operations described in greater detail herein. Once data enrichment operations have been completed, the process 808 component is likewise implemented to interact with the filter/transform 824 component, which in turn is implemented to perform data filtering and transformation operations described in greater detail herein.

In various embodiments, the process 808 component is implemented to generate various models, described in greater detail herein, which are stored in the repository of models 828. The process 808 component is likewise implemented in various embodiments to use the sourced data to generate one or more cognitive graphs, such as an application cognitive graph 882, as described in greater detail herein. In various embodiments, the process 808 component is implemented to gain an understanding of the data sourced from the sources of social data 812, public data 814, licensed data 816, and proprietary data 818, which assist in the automated generation of the application cognitive graph 882.

The process 808 component is likewise implemented in various embodiments to perform bridging 846 operations, described in greater detail herein, to access the application cognitive graph 882. In certain embodiments, the bridging 846 operations are performed by bridging agents, likewise described in greater detail herein. In various embodiments, the application cognitive graph 882 is accessed by the process 808 component during the learning 836 phase of the composite cognitive insight generation operations.

In various embodiments, a cognitive application 304 is implemented to receive input data 842 associated with an individual user or a group of users. In these embodiments, the input data 842 may be direct, such as a user query or mouse click, or indirect, such as the current time or Geographical Positioning System (GPS) data received from a mobile device associated with a user. In various embodiments, the indirect input data 842 may include contextual data, described in greater detail herein. Once it is received, the input data 842 is then submitted by the cognitive application 304 to a graph query engine 326 during the application/insight composition 840 phase. In turn, the graph query engine 326 processes the submitted input data 842 to generate a graph query 844, as described in greater detail herein. The graph query 844 is then used to query the application cognitive graph 882, which results in the generation of one or more composite cognitive insights, likewise described in greater detail herein. In certain embodiments, the graph query 844 uses predetermined knowledge elements stored in the universal knowledge repository 880 when querying the application cognitive graph 882 to generate the one or more composite insights.

In various embodiments, a set of contextually-related interactions between a cognitive application 304 and the application cognitive graph 882 are represented as a corresponding set of nodes in a predetermined cognitive session graph, which is then stored in a repository of cognitive session graphs ‘1’ through ‘n’ 852. As used herein, a cognitive session graph broadly refers to a cognitive graph whose nodes are associated with a cognitive session. As used herein, a cognitive session broadly refers to a predetermined user, group of users, theme, topic, issue, question, intent, goal, objective, task, assignment, process, situation, requirement, condition, responsibility, location, period of time, or any combination thereof.

As an example, the application cognitive graph 882 may be unaware of a particular user's preferences, which are likely stored in a corresponding user profile. To further the example, a user may typically choose a particular brand or manufacturer when shopping for a given type of product, such as cookware. A record of each query regarding that brand of cookware, or its selection, is iteratively stored in a predetermined cognitive session graph that is associated with the user and stored in a repository of cognitive session graphs ‘1’ through ‘n’ 852. As a result, the preference of that brand of cookware is ranked higher, and is presented in response to contextually-related queries, even when the preferred brand of cookware is not explicitly referenced by the user. To continue the example, the user may make a number of queries over a period of days or weeks, yet the queries are all associated with the same cognitive session graph that is associated with the user and stored in a repository of cognitive session graphs ‘1’ through ‘n’ 852, regardless of when each query is made.

As another example, a user queries a cognitive application 304 during business hours to locate an upscale restaurant located close their place of business. As a result, a first cognitive session graph stored in a repository of cognitive session graphs ‘1’ through ‘n’ 852 is associated with the user's query, which results in the provision of composite cognitive insights related to restaurants suitable for business meetings. To continue the example, the same user queries the same cognitive application 304 during the weekend to locate a casual restaurant located close to their home. As a result, a second cognitive session graph stored in a repository of cognitive session graphs ‘1’ through ‘n’ 852 is associated with the user's query, which results in the provision of composite cognitive insights related to restaurants suitable for family meals. In these examples, the first and second cognitive session graphs are both associated with the same user, but for two different purposes, which results in the provision of two different sets of composite cognitive insights.

As yet another example, a group of customer support representatives is tasked with resolving technical issues customers may have with a predetermined product. In this example, the product and the group of customer support representatives are collectively associated with a predetermined cognitive session graph stored in a repository of cognitive session graphs ‘1’ through ‘n’ 852. To continue the example, individual customer support representatives may submit queries related to the product to a cognitive application 304, such as a knowledge base application. In response, a predetermined cognitive session graph stored in a repository of cognitive session graphs ‘1’ through ‘n’ 852 is used, along with the universal knowledge repository 880 and application cognitive graph 882, to generate individual or composite cognitive insights to resolve a technical issue for a customer. In this example, the cognitive application 304 may be queried by the individual customer support representatives at different times during some predetermined time interval, yet the same cognitive session graph stored in a repository of cognitive session graphs ‘1’ through ‘n’ 852 is used to generate composite cognitive insights related to the product.

In various embodiments, each cognitive session graph associated with a user and stored in a repository of cognitive session graphs ‘1’ through ‘n’ 852 includes one or more direct or indirect user queries represented as nodes, and the time at which they were asked, which are in turn linked 854 to nodes that appear in the application cognitive graph 882. In certain embodiments, each individual session graph that is associated with the user and stored in a repository of cognitive session graphs ‘1’ through ‘n’ 852 introduces edges that are not already present in the application cognitive graph 882. More specifically, each of the session graphs that is associated with the user and stored in a repository of cognitive session graphs ‘1’ through ‘n’ 852 establishes various relationships that the application cognitive graph 882 does not already have.

In various embodiments, individual graph queries 844 associated with a predetermined session graph stored in a repository of cognitive session graphs ‘1’ through ‘n’ 852 are likewise provided to predetermined insight agents to perform various kinds of analyses. In certain embodiments, each insight agent performs a different kind of analysis. In various embodiments, different insight agents may perform the same, or similar, analyses. In certain embodiments, different agents performing the same or similar analyses may be competing between themselves.

For example, a user may be a realtor that has a young, upper middle-class, urban-oriented clientele that typically enjoys eating at trendy restaurants that are in walking distance of where they live. As a result, the realtor may be interested in knowing about new or popular restaurants that are in walking distance of their property listings that have a young, middle-class clientele. In this example, the user's queries may result the assignment of predetermined insight agents to perform analysis of various social media interactions to identify such restaurants that have received favorable reviews. To continue the example, the resulting composite insights may be provided as a ranked list of candidate restaurants that may be suitable venues for the realtor to meet his clients.

In various embodiments, the process 808 component is implemented to provide these composite cognitive insights to the deliver 810 component, which in turn is implemented to deliver the composite cognitive insights in the form of a cognitive insight summary 848 to the cognitive application 304. In these embodiments, the cognitive platform 810 is implemented to interact with an insight front-end 856 component, which provides a composite insight and feedback interface with the cognitive application 304. In certain embodiments, the insight front-end 856 component includes an insight Application Program Interface (API) 858 and a feedback API 860, described in greater detail herein. In these embodiments, the insight API 858 is implemented to convey the cognitive insight summary 848 to the cognitive application 304. Likewise, the feedback API 860 is used to convey associated direct or indirect user feedback 862 to the cognitive platform 810. In certain embodiments, the feedback API 860 provides the direct or indirect user feedback 862 to the repository of models 828 described in greater detail herein.

To continue the preceding example, the user may have received a list of candidate restaurants that may be suitable venues for meeting his clients. However, one of his clients has a pet that they like to take with them wherever they go. As a result, the user provides feedback 862 that he is looking for a restaurant that is pet-friendly. The provided feedback 862 is in turn provided to the insight agents to identify candidate restaurants that are also pet-friendly. In this example, the feedback 862 is stored in the appropriate cognitive session graph stored in a repository of cognitive session graphs ‘1’ through ‘n’ 852 associated with the user and their original query.

In various embodiments, as described in the descriptive text associated with FIG. 5, learning operations are iteratively performed during the learning 838 phase to provide more accurate and useful composite cognitive insights. In certain of these embodiments, feedback 862 received from the user is stored in a predetermined cognitive session graph that is associated with the user and stored in a repository of cognitive session graphs ‘1’ through ‘n’ 852, which is then used to provide more accurate composite cognitive insights in response to subsequent contextually-relevant queries from the user.

As an example, composite cognitive insights provided by a particular insight agent related to a first subject may not be relevant or particularly useful to a user of the cognitive application 304. As a result, the user provides feedback 862 to that effect, which in turn is stored in the appropriate cognitive session graph that is associated with the user and stored in a repository of cognitive session graphs ‘1’ through ‘n’ 852. Accordingly, subsequent insights provided by the insight agent related the first subject may be ranked lower, or not provided, within a cognitive insight summary 848 to the user. Conversely, the same insight agent may provide excellent insights related to a second subject, resulting in positive feedback 862 being received from the user. The positive feedback 862 is likewise stored in the appropriate cognitive session graph that is associated with the user and stored in a repository of cognitive session graphs ‘1’ through ‘n’ 852. As a result, subsequent insights provided by the insight agent related to the second subject may be ranked higher within a cognitive insight summary 848 provided to the user.

In various embodiments, the composite insights provided in each cognitive insight summary 848 to the cognitive application 304, and corresponding feedback 862 received from a user in return, is provided in the form of one or more insight streams 864 to an associated cognitive session graph stored in a repository of cognitive session graphs ‘1’ through ‘n’ 852. In these and other embodiments, the insight streams 864 may contain information related to the user of the cognitive application 304, the time and date of the provided composite cognitive insights and related feedback 862, the location of the user, and the device used by the user.

As an example, a query related to upcoming activities that is received at 10:00 AM on a Saturday morning from a user's home may return composite cognitive insights related to entertainment performances scheduled for the weekend. Conversely, the same query received at the same time on a Monday morning from a user's office may return composite insights related to business functions scheduled during the work week. In various embodiments, the information contained in the insight streams 864 is used to rank the composite cognitive insights provided in the cognitive insight summary 848. In certain embodiments, the composite cognitive insights are continually re-ranked as additional insight streams 864 are received. Skilled practitioners of the art will recognize that many such embodiments are possible and the foregoing is not intended to limit the spirit, scope or intent of the invention.

FIG. 9 is a generalized flowchart of composite cognitive insight and feedback operations performed in accordance with an embodiment of the invention. In this embodiment, composite cognitive insight and feedback operations are begun in step 902, followed by a cognitive application requesting an Application Programming Interface (API) key from a cognitive platform, described in greater detail herein, in step 906. The method by which the API key is requested, generated and provided to the cognitive application is a matter of design choice.

A cognitive session token is then issued to the cognitive application in step 906, followed by a cognitive session token being returned to the cognitive application in step 908 to establish a composite cognitive insight session. As used herein, a composite cognitive insight session broadly refers to a session with a cognitive application, described in greater detail herein, where composite cognitive insights are generated and presented to a user. In various embodiments, the composite cognitive insight session may also include the receipt of feedback from the user, described in greater detail herein. In one embodiment, the cognitive session token is used to establish a composite cognitive insight session that generates a new cognitive session graph. In another embodiment, the cognitive session token is used to establish a composite cognitive insight session that appends composite cognitive insights and user feedback to an existing cognitive session graph associated with the user.

In various embodiments, the cognitive session token enables the cognitive application to interact with a cognitive session graph associated with the cognitive session token. In these embodiments, the composite cognitive insight session is perpetuated. For example, a given composite cognitive insight session may last months or even years. In certain embodiments, the cognitive session token expires after a predetermined period of time. In these embodiments, the cognitive session token is no longer valid once the predetermined period of time expires. The method by which the period of time is determined, and monitored, is a matter of design choice.

Contextually-relevant composite cognitive insights are then generated and presented, as described in greater detail herein, to the user in step 910. In various embodiments, composite cognitive insights presented to the user are stored in the cognitive session graph associated with the cognitive session token. A determination is then made in step 912 if feedback is received from the user. If not, then a determination is made in step 924 whether to end composite cognitive insights and feedback operations. If not, then a determination is made in step 926 whether the cognitive session token for the target session has expired. If not, then the process is continued, proceeding with step 910. Otherwise, the process is continued, proceeding with step 904. However, if it is determined in step 924 not to end composite cognitive insights and feedback operations, then composite cognitive insights and feedback operations are ended in step 928.

However, if it was determined in step 912 that feedback was received from the user then the cognitive application provides the feedback, as described in greater detail herein, to the cognitive platform in step 914. A determination is then made in step 916 whether to use the provided feedback to generate contextually-relevant questions for provision to the user. If not, then the process is continued, proceeding with step 924. Otherwise, the cognitive platform uses the provided feedback in step 918 to generate contextually-relevant questions. Then, in step 922, the cognitive platform provides the contextually-relevant questions, along with additional composite insights, to the cognitive application. In turn, the cognitive application provides the contextually-relevant questions and additional composite cognitive insights to the user in step 922 and the process is continued, proceeding with step 912.
